fair question. answer - yes.
I've got a hand held pH meter that I use to corroborate the readings of my in-tank meterA couple of weeks ago I did a 2-point calibration of the hand held, and then tested it against reference solutions. It reads pretty accurate, and it agrees (within a small tolerance) of the reading of the in-tank meter.
As for KH, that's a little fuzzier, though I do have a Lamotte test kit which provides very precise (accurate?) results. And I use a 2nd, LFS quality, test kit to corroborate the results of that Lamotte.
In short, when I factor in margin of error, it's possible that my CO2 is as low as 24 ppm. Or it could be as high as 39. I guess a slight boost would be ok. But I'm not one to crank CO2 as an algaecide. My minimum (worst case) should be enough to support healthy, well lit, fertilized plants.
Though a small boost wouldn't hurt. Thanks.

Swords and crypts wont to diddly to absolve these issues.

Good point Buck. Thanks. I've got some pretty big hunks of Taiwan moss - total volume of about the size of one and a half basketballs - that should be soaking up stuff from the water column. Something is soaking it up, because if I don't dose NPK, is drops pretty precipitously.
But I will look for a short term, fert soaking possibility. Thanks.
